Benefits of technology

[0009]It would be advantageous to provide an insertion instrument for deploying spinal implants that can be easily disassembled for cleaning and assembled for use.

Problems solved by technology

Over time, the ligaments and bone that surround the spinal canal can thicken and harden, resulting in a narrowing of the spinal canal and compression of the spinal cord or nerve roots.
This condition is called spinal stenosis, which results in pain and numbness in the back and legs, weakness and / or a loss of balance.
While some patients may experience relief from symptoms of spinal stenosis with such treatments, many do not, and thus turn to surgical treatment.

Abstract

An insertion device for deploying an implant includes an elongated main body having a distal locking portion for coupling to the implant and a proximal handle portion. The main body defines a central passage and the distal locking portion has outer ridges and slots to allow the outer ridges to flex radially inward when mounting to the implant. A plunger slides in the central passage for movement between an unlocked position for mounting the implant on the distal locking portion, a locked position for locking the implant on the distal locking portion, and an insertion instrument deployed position for deploying the actuation plunger to move the blades from the stowed position to the deployed position. A spike cap drive rotatably mounts on the main body having a socket end for engaging a drive nut on the implant to, in turn, move the spike cap.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority to U.S. Patent Application Ser. No. 61 / 828,384, filed May 29, 2013, which application is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The subject technology is directed to instruments for inserting spinal implants, and more particularly, to an insertion instrument that is easily assembled and disassembled for required cleaning while being able to effectively deploy an interspinous process implant for spinal stabilization, for percutaneous placement in a target interspinous process space, wherein the implant can also serve as a fusion cage spacer to treat lumbar spinal stenosis.[0004]2. Description of Related Art[0005]The spine consists of a column of twenty-four vertebrae that extend from the skull to the hips. Discs of soft tissue are disposed between adjacent vertebrae. The vertebrae provide support for the head and body, ...
